Player destroys when he touches particle effect.

Hi,im making lasers in my game,well i tried everything to get this work,but nothing,i want my player destroys when he touches laser.If i add mesh collider or rigibody to laser,it just goes crazy and is no longer usable,so is there any other way without adding anything,please help me? How can i Make Player Destroys when he touches laser?

Imagine the laser is a raycast. So just raycast in the same direction and angle as the laser, and what the laser touches, you can find out with the hit info of the raycast.
